Sorry about the anonymous postings earlier. I didn't realize that the forumware wouldn't continue my user ID for replies.

In any event, it looks like this is a hard-coded feature of the server. From the CommuniGate docs:

"The IMAP module supports the STARTTLS command that allows client mailers to establish a connection in the clear text mode and then turn it into a secure connection."

So even though I have "init STARTTLS NO", that apparently just means TLS isn't required, but will be accepted from a client. Is there any way to get Xeams to not try upgrading to TLS on port 143?
